Imaginary chemical potential quantum Monte Carlo for Hubbard molecules
Fei Lin, Jurij Smakov, Erik S. Sorensen +2
We generalize the imaginary chemical potential quantum Monte Carlo (QMC) method proposed by Dagotto et al. [Phys. Rev. B 41, R811 (1990)] to systems without particle-hole symmetry.…
QMC Calculation of the Electronic Binding Energy in a C60 Molecule
Fei Lin, Jurij Smakov, Erik S. Sorensen +2
Electronic energies are calculated for a Hubbard model on the molecule using projector quantum Monte Carlo (QMC). Calculations are performed to accuracy high enough to det…
Ordering and Spin Waves in NaNiO2 : A Stacked Quantum Ferromagnet
M. J. Lewis, B. D. Gaulin, L. Filion +5
Neutron scattering measurements on powder NaNiO2 reveal magnetic Bragg peaks and spin waves characteristic of strongly correlated s=1/2 magnetic moments arranged in ferromagnetic l…
High Resolution Study of Spin Excitations in the Shastry-Sutherland Singlet Ground State of SrCu2(BO3)2
B. D. Gaulin, S. H. Lee, S. Haravifard +5
High resolution, inelastic neutron scattering measurements on SrCu2(BO3)2 reveal the dispersion of the three single triplet excitations continuously across the (H,0) direction with…
